Rush Street Interactive (NYSE: RSI) is a market leader in online casino and sports betting, currently operating real-money gaming with our brands: BetRivers.com, PlaySugarHouse.com, and RushBet.co.

We are a mobile-first organization evolving our digital platform toward a modern, scalable, event-driven architecture. As a Sr. Front End Engineer, you will play a foundational role in building and evolving our client applications and the event orchestration architecture that powers them.

You will work in close coordination with feature-delivery teams to ensure instrumentation and orchestration standards are embedded directly into product development. In parallel, you will help shape the long-term evolution of our client event architecture.

This position requires deep frontend and mobile expertise combined with systems thinking, architectural rigor, and a strong understanding of scalable event-driven systems.

Cross-Functional

• Partner closely with Product, Analytics, and Engineering teams to align instrumentation and architecture with business objectives.
• Participate in architectural discussions that shape long-term platform modernization.
• Balance ongoing support needs with forward-looking architectural improvements.

• Strong proficiency in React, Angular, TypeScript, and native iOS/Android development.
• Proven experience implementing analytics or CDP SDKs within mobile applications.
